The Breadline Unit focused on how people reacted to the Great Depression. Despite these numerous benefits, however, the New Deal ultimately failed to end the Great Depression. More than ten years after the Crash of 1929, millions of Americans were still hungry, homeless, and unemployed. Some historians argue that Roosevelt could have ended the depression completely if he had put more federal dollars into the economy, but this conclusion is debatable. The depression ended only after the United States entered World War II in 1941, when the increased demand for wartime commodities such as ships, tanks, and munitions gave the U.S. economy the jump start it needed.
